Answer:
The total charge on atom is -2.
Step-by-step explanation:
We are given the following in the question:
Electrons have a negative charge.
Let this charge be represented by -1.
Protons have a positive charge. Let this charge be represented by +1.
An atom have 2 more electrons than protons.
Let
be the number of protons.
Then, the number of electrons are 
Total charge on atom =
=Charge on atom = Charge of protons + Charge of electrons

Thus, the total charge on atom is -2.
